Depending on your linux version, you may be able to download this file, e.g.
http://www.novell.com/products/linuxpackages/enterpriseserver/x86-64/gmp.html

As you can see on that page, it would normally be a symlink to a file of 
the same name with subversion numbers appended.

I have had to build it from source, for several of my installations, 
even one where a matching library file was available, but apparently 
corrupted.
